The original was a little too much gone inside, I honed it, but there still was some corrosion.
So, I bought new aftermarket one and dismantled it. There was few differences, look at the caps between the C-clip and plastic (left new, right old):
Also one seal was missing, not even place for it:
Also the valves missing:
So, I installed the new ABE master cylinder with the old OEM inserts:
Also old cap refreshed with WD40 (because no sensor in the new one):
Heater core is washed, cleaned, new seals and a little new paint.
The power steering reservoir is found it’s place:
Holes are made for the PTO handle and hand brake lever:
Steering wheel looks suitable for me. I modified the blue center T-logo piece to work as horn:
Fuel filling/breather pipes are installed:
The trailer connector wires are plugged (13-pin Euro-model socket):
Hand brake cable routing:
I drilled new hole for the link that the cable reach better:
